IMPRovED Livres;A

The Schedule referred to in these Letters Patent` and making part of the same.

To all whom it may concern Be it known that I, FREDERICK W.GAMMELL, of p Spring Valley, in `the county of Decatur, and State of Iowa, have invented a new and improved Door Rest; and I do hereby declare that the following is a full, clear, andl exact descliptiou thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this'specificatiou, in which--v Figure 1 is a front view of a-door, to which my improved rest has been applied. v

Figure 2 is a detail sectional view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to support the door.

when closed, soa-s to prevent the door iorn sagging or warping, and whichsball be simple in construction and easily applied to the door.

A represents the door-casing, and B represents the' door, about the construction of which parts there is nothing new.

C is a plate, which is let into the casing A, so that its outer `surface may be flush with thesurface of the said casing.

Upon the outer side of the plate O are formed two brackets, having notches in their upper edges, to serve,

as bearings for'the roller D.

E is the catch, which is securely attached to the door B, and which should be so arranged, that when the door is closed, it may just pass the axis of the roller D, and thus tend tov revolve said roller towardl the door-casing, and thus/bold the door to its place.

One or more of the rests C D E may be used, ac-

cording to the character of the door, and they should Y K from cutting the door-casing.

Fis a cap or socket-plate. attached to the door, near its forward corner. v

G is ashai't or stem, which enters the socket of the plate F, and is held out by a coiled spring, H, placed within the said socket.

To the lower or projecting end ofthe stem G is pivoted a roller, I, the face of which should be slightly rounded off, to prevent the said roller from cutting the carpet or iloor along which it rolls.

J is a plate, which is attached to the carpet-strip and which is vmade wit-h a sink or recess, so that the roller I, when the door is closed, may incline to roll down into said sink or recess, aud thus hold the door toits place.

K isa lock, which is pivoted to the casing A, in such a position that when the door is closed, it may be turned down against the latch E, and thus lock the door.

The plate C should extend up above the latch E, so that it may serve as avwasher to prevent the lock I am aware that a patent was granted to B. Hendrickson, December 15, 1868, in which isA shown a gate, with a friction-roller upon it, acting in combination with a plate, recessed and inclined on each side,

but Ihave no intention of claiming the same.

Having thus described my invention,

I claim as new, land desire'to secure by Letters Patent'- 1. A door and casing, A B, provided with the fixed latch E, lixed plate 0,'and friction-roll D, arranged and operating together in the manner described.

2. A door and casing, Al B, provided with the xed latch E, fixed plate 0, friction-roll D, and ,swinging 4arm K, arranged as and for the -purpose specified.
